“Just replaced my expansion tank and added this valve. 100% worth it to make it easy to drain the tank and check the pressure whenever needed. Also makes it easier to change an empty tank vs one with 5 gallons of water in it! Worth the price and cheaper than building a drain set up from other parts.”
“This is a must if you're installing a new system or existing system or the thermal expansion tank. Doesn't add much length to the system. Works well for us.”
“Attaches between expansion tank and air eliminator to remove air before it even enters your system. 1/2" fittings for expansion tank, air eliminator, boiler fill valve, and even a capped drain hose connection and two isolation valves. Solves so many problems with a single rust-free brass part.”
